上顎洞に発生し広範囲に転移したMalignant fibrous histiocytomaの一剖検例

抄録

A case of primary malignant fibrous histiocytoma of the maxillary sinus occurring in a 41-year-old woman is described.
This neoplasm spread rapidly and the patient died 17 months after surgery. At autopsy, widespread metastases involving the lung, thorax, kidney, vertebrae and brain were found.
Malignant fibrous histiocytoma frequently occurs in the extremity, trunk and retroperitoneum. It rarely occurs in the paranasal sinus.
It's histological origin remains controversial.
